Cool! I'm customizing mine, but even using primer and acrylic paint I have had problems in use, because the ink spoils with little time. I'm trying to use varnish to improve the fixing. But I not do professionally, I'm from Brazil and here who do not have professional way, I'm only in my doing. Could you tell me what kind of product use for painting?

I use Krylon spray paints. You can use google to figure out the best way to apply it. I am always learning something new! Are you applying clearcoat after your acrylic? That may be why your paint is spoiling over time. Try using Duplicolor Perfect Match clear (Acrylic Lacquer). Your paint job will then be protected.

I wish you good luck! These are very fun to do once you get the hang of it

Yes, I am testing the varnish after acrylic. Think it will give a good result, leaving the more durable paint. I use the airbrush to paint the design. The best primer I found was the COLORGIN, is very sturdy but a bit difficult to apply and use. And to improve the fixation of the primer I trash the original surface before applying to take the shine off the plastic. But I will look for Duplicolor Perfect Match. Thanks for the tip.

Good luck to you too, his works are very, very good! The Zelda theme is amazing!
